They don't bother my tomato and pepper plants at all, I don't bother to cage those, nor okra, squashes, beans. As I said, they eat some of the low hanging tomatoes. Mainly the cages are for my cold weather veggies. I do have livestock fence around the garden to keep deer out but anything smaller can go right under..You're lucky. Critters eat EVERYTHING in my garden. All parts of the plants and at all kinds of heights. Also, my tomato and pepper plants are as tall as me, so it's hard to put cages around them and be able to remove them to pick ripe fruit... And I have lots of plants, too - 30 pepper plants, 15 tomato plants, etc. so it's impractical to cage individual plants. So I'm looking for a way to cover the entire garden up and be able to walk inside and pick easily.
